And (4) round: preferably, each scheduling scheme of the system can obtain 500 programs to form a playlist, generally, one scheduling scheme is far less than 500 slots, so that multiple rounds are available, and fragments of each round are in accordance with the sequence and content range of the scheduling bits under the scheduling scheme until 500 programs are obtained.
The embodiment provides an arrangement and display system of audio radio streams, which comprises a database 1, a main broadcasting station, a media resource system 2, a broadcasting list generating system 3, a background configuration management system 4, a configuration interface and a user display interface.
The arranging and displaying system is firstly configured by a background configuration management system 4 through a configuration interface to generate an arranging scheme of each radio station in each time period, and the arranging scheme is stored in a database, preferably a db database; simultaneously, each audio program is stored in a database, preferably a db database, through the main broadcasting station and the media resource system 2, and is stored according to the structure of program fragment → album → classification; then generating a default playlist: the configured information of the radio station, the arrangement scheme and the like is loaded into a memory at one time through a broadcast list generating system 3, the programs, the albums, the classified IDs, the incidence relations and the like are also loaded into the memory, a default broadcast list is calculated through the rules of time effectiveness, weight, album fragment sequencing, duplicate removal and the like, and is stored in a database, preferably a database redis; and then generating a user play list: after the default playlist is generated every time, the arranging and displaying system finds the users who hear the radio station within a week, refreshes the arranged user playlists of the users, finds the arranging scheme of the corresponding time period if the corresponding users cannot be found, takes the corresponding default playlist as the user playlist, and stores the user playlist into a database redis; due to the attributes of interest, regions and the like of the users and the difference of listening and browsing conditions, the play lists generated by different users are different; the playlist update logic is: when the arranged content or the audio content changes, the arranging and displaying system can refresh the default playlist and the user playlist which are correspondingly arranged at each time interval in time, so that new content can quickly appear in the user playlist and be listened by the user; the pre-generated default playlist and the user playlist only do space occupation logic, and the targeted release content of the push content is generated in real time on the user display interface. Remote Dictionary Server (Remote Dictionary service) is an open source log-type and Key-Value database written in ANSI C language, supporting network, based on memory and persistent, and provides API of multiple languages. The system as a whole and the flow are shown in fig. 2.
The arrangement and presentation system generates a playlist considering how to take out suitable fragments under corresponding conditions and determines the sequence of acquiring programs from a candidate set, and the sequence is mainly divided into two dimensions: one dimension is on the radio station level, is divided into an aging radio station and a weight radio station, and can be expanded into other regular radio stations; the other dimension is in a content layer configured on the arrangement position and is divided into albums, common classifications, station-announcement classifications, song classifications, region classifications, personalized classifications and recommendation classification rules, and the other types can be expanded and configured.
The implementation logic of the aging radio station comprises: when a background management system has a radio station, an arrangement scheme, an arrangement position and the like which influence the change of a playlist generation logic rule or a new audio content changes, the arrangement and display system calls a trigger playlist update logic, a playlist generation system 3 loads the arrangement rule and content information of the radio station into a memory according to needs, circularly generates a default playlist of each arrangement scheme and all user playlists under the arrangement scheme, generates rules according to the following text each time, and stores the default playlist and the user playlists in a database redis; and after the generation of the play list is finished, the user requests the play list data, displays the play list and listens.
The logic for generating the default playlist for each orchestration scheme in a loop comprises: loading all the editing positions of the editing scheme, calculating which fragment each editing position should display, and determining the number of times of generating the play list according to the play list and the number of the editing positions; preferably, considering that the playlist is generated 500, and the program bit is only 50, 10 rounds of playlists are generated. In order to ensure the effect of the playlist presentation, the global audio fragments are deduplicated, so a cache structure is maintained simultaneously in the cyclic generation process, and one audio fragment is generated and recorded in the cache structure every time, so that the global fragments are not repeated; calculating a display rule of each editing position for each turn when generating the playing list, wherein the display rule is different according to different configured content types and sequentially comprises a single album, a common classification, a channel or song classification, a region classification, a personalization and recommendation classification and the like configured by the editing positions; the album extraction rule, the general classification rule, the song classification logic, the directional release classification logic, and the like are described below. In order to ensure the effect of playing the list, the albums in each turn are deduplicated, so a cache structure is maintained in the cycle at the same time, and the corresponding albums are recorded into the cache structure after an audio fragment is generated each time, so that the albums in each turn are not repeated.
When the placement is a single album, the audio for that placement is as follows: screening fragments which are online within 24h, and taking out the fragments which are online within 24h from the albums meeting the conditions by the first carousel; when all the updated program fragments in 24h on the editing position are taken out, the fragments on line in 24h can be taken out, and meanwhile, screening is carried out according to the filtering condition necessary for the system, such as the on-line state of the fragments and the like; the shards within the album are sorted according to the time of the line, with the line time being ahead of the current nearest and behind the far.
When the allocation of the editing bits is a general classification, the audio frequency of the editing bits is extracted according to the following steps: the albums are classified and configured, so that the albums are screened firstly, the albums with updated fragments in 24h are screened out, the albums with the updated fragments in 24h away from the current time in the playlist are taken out, the albums updated in 24h can be taken out recursively after all the programs updated in 24h on the arrangement position are taken out, meanwhile, the unmatched albums are filtered according to the system necessary conditions including the scores and the online states of the albums, then screening is carried out according to the ordering rule, the fragment taking-out rule is also required to be considered, and then the fragments are taken out sequentially according to the album sequence; the sequencing rule is as follows: the albums are sorted according to the scores, the score is large in the front, and the score is small in the rear (logically, the score of 5 is 4-3); the scores are the same, and the scores are sorted according to the last updating time, wherein the updating time is arranged in front of the current row, and the updating time is arranged behind the current row; the updating time is the same, and the albums are sorted according to the IDs, wherein the IDs are arranged in the front and the IDs are arranged in the back; the fragment extraction rule is as follows: screening fragments which are online in 24h, taking out the fragments which are online in 24h from the album meeting the conditions by the first carousel, taking the fragments which are online in 24h forward after all the updated program fragments in 24h on the editing and arranging position are taken out, and simultaneously, screening according to the system necessary filtering conditions including the online states of the fragments and the like, and sequencing the screened fragments in the album; the fragment sorting in the album is to sort the fragments in the album according to the online time, wherein the online time is arranged in front of the current position close to the current position, and the far position is arranged behind the current position; taking the fragments in sequence according to the album sequence: taking the first fragment meeting the conditions in the second album; after all the albums are taken out, taking the second fragment meeting the conditions from the first album, and so on; if no eligible shards exist in an album, the shards in the album are removed in album order.
When the position arrangement is station announcement or song classification, the audio of the position is taken according to the following steps: screening out the audio fragments of the station announcements or songs which are in an online state and meet the inflow conditions, correspondingly classifying and taking out the audio fragments, recording the IDs of the taken-out audio fragments, filtering out the recorded IDs of the fragments when taking out the audio fragments from the next position, and randomly taking out the fragments from the rest; and when all the fragments are taken out, namely all the fragments are filtered, clearing the records, randomly taking the fragments under the labels again, and circulating in sequence.
When the arrangement position configuration is a region classification, the position takes the audio frequency according to the following steps: forming a placeholder at the position, recording a candidate audio fragment set at the position, and calculating corresponding audio fragments in real time to form a play list when a user side requests that the user side carries a vehicle type and a region (such as Beijing); when the arrangement position configuration is personalized and recommended to be classified, the position is used for taking the audio frequency according to the following steps: and forming a placeholder at the position, and calling a recommendation system to generate the playlist in real time when the user side requests the playlist list.
For the above process steps of the aging rule, reference is made for example to fig. 3. Fig. 3 illustrates a schematic diagram of an arrangement with only three positions, A, B, C, D, E, F, G indicating albums, a1, B1, C1, C2, E1, F1, F2, G1 indicating corresponding audio pieces under each album. The method comprises the steps of respectively carrying out common classification, album sorting and common classification, carrying out album screening, album sorting and fragment sorting, and finally forming a default wave playlist, wherein the default wave playlist is formed in three turns, and the finally formed playlists are C1, E1, F1, C2, F2, A1, G1 and B1.
After the default playlist of each arrangement time interval is generated according to the process, the user playlist of each time interval is generated, and the process is as follows: copying the default playlist into the playlists of all users, and continuing to configure each playlist according to the above rules of single album, common classification, station announcement or song classification and region classification from the arrangement position until fragments are taken out according to the rules of personalization and recommended classification, wherein the different is that audio contents listened to by the users and browsed contents need to be filtered; the strategy of listening and filtering ensures that a user does not listen to repeated fragments any more, the record of listening and filtering is recorded according to the dimension of equipment ID + radio station ID, the record is recorded into a database redis by a storm streaming processing program in a data reporting mode, when a user play list is generated, the record of listening and filtering in the database redis is read, the listened fragments are filtered, and new fragments meeting the conditions are taken out; the strategy of browsing and filtering ensures that after the radio station is repeatedly entered, the repeated content is not displayed in the radio station, and the content is recorded in the database redis. The storm is a distributed and fault-tolerant real-time computing system, follows Eclipse publishing license.0, can be conveniently compiled and expanded into complex real-time computing in a computer cluster, and is processed in real time, namely just batch processing of btHadoop; storm ensures that every message is processed and very fast, in a small cluster, millions of messages can be processed per second; any programming language may also be used for development.
